P2287 — Injector Control Pressure Sensor Circuit Intermittent

Manufacturer-specificPowertrain (engine & transmission)

The P2287 code indicates that the engine control module has detected an intermittent electrical signal from the injector control pressure sensor. This means the circuit is momentarily breaking or fluctuating outside of the expected voltage range, rather than being completely open or shorted.

Symptoms

What causes it — most likely first

1. Faulty Pressure Sensor

Internal failure of the sensor's circuitry causing intermittent signal drops.

2. Wiring Harness Damage

Frayed, rubbed, or corroded wires causing a temporary loss of connection.

3. Corroded Connector

Moisture or debris in the sensor plug causing poor electrical contact.

4. Loose Ground Connection

A loose or oxidized ground wire affecting the sensor's reference voltage.

5. PCM Failure

Internal failure of the engine control module's processing circuit for the sensor.

How it's diagnosed

  1. Perform a visual inspection of the sensor connector and wiring for signs of wear or corrosion.
  2. Use a scan tool to monitor the fuel rail pressure live data for erratic jumps or dropouts.
  3. Perform a 'wiggle test' on the wiring harness while monitoring data to identify intermittent breaks.
  4. Measure the reference voltage at the sensor connector to ensure the PCM is providing steady power.
  5. Test the sensor's signal return voltage using a multimeter or oscilloscope to verify waveform stability.
  6. Verify the sensor's resistance and grounding according to manufacturer specifications.

Frequently asked

Can a mechanical fuel pump failure cause P2287?

Generally no. P2287 is a circuit code, meaning the problem is electrical. A pump failure usually triggers codes related to low pressure rather than an intermittent circuit.

Should I replace the PCM if I have this code?

No. It is very uncommon for the PCM to be the cause of P2287. Wiring issues and sensor failure are far more frequent causes and should be ruled out first.

Is this code critical for engine safety?

Yes, as erratic pressure readings can lead to incorrect fuel injection timing, potentially causing engine stalling or poor combustion.
